Bean products, such as tofu and soybean milk, are a common food in our daily life and a health food recommended by nutritionists every day.
But recently, when men reach middle age, if they don't eat such food, it will affect their functions. It is also said that women who eat too much soybeans and products will easily lead to breast cancer.
These statements come from phytoestrogens in soybeans called soybean isoflavones. When men reach middle age, their naturally secreted androgens begin to decrease. In this case, a large amount of estrogen intake will have a certain impact on their functions. Women eat too much soy and its products, and estrogen intake is too much, which increases the risk of breast cancer.
Although this explanation seems reasonable, if you analyze it carefully, you will find that there are big problems.
There are many benefits for men to eat beans
First of all, the history of eating soybeans in China has a very long history. We have never seen a record of eating soybeans, male dysplasia or feminization.
Soy bean isoflavone, the so-called estrogen in soybeans, has only one thousandth of human estrogen's biological activity. Moreover, male androgen content is very high. Phytoestrogen in a cup of soybean milk is impossible to reverse hormone balance and affect male sexual characteristics.
In the latest version of the dietary guide, the Chinese Nutrition Society recommends that each person should consume 30-50 grams of soybeans or equivalent amounts of soy products every day. Based on the proportion of 4000g soybean milk ground with 500g soybeans, or 1750g tofu made with 500g soybeans, 50g soybeans is equivalent to two cups of soybean milk, or one cup of soybean milk plus a small piece of tofu. This number will certainly not feminize Chinese men and will not reduce fertility.
On the contrary, after two generations, the incidence rate of prostate cancer of Japanese men who emigrated to the United States was significantly higher than that of Japanese men, which was related to the reduced intake of soy products after immigration. Therefore, phytoestrogens in soybean can inhibit the production of testosterone, an important substance that can induce male prostate cancer.
So, men, please rest assured to eat soybeans!
Two-way regulation, stable estrogen
In the same way, only one thousandth of estrogen can increase the risk of breast cancer.
On the contrary, under the condition of high estrogen level in the human body, soybean isoflavones occupy the receptor position of estrogen in a competitive way, achieving the effect of resisting estrogen (equivalent to offsetting the estrogen function of 9.99%), and inhibiting the reproduction of estrogen dependent tumors (breast cancer, etc.). At the same time, it can also inhibit gastrointestinal tumors, liver cancer, prostate cancer and other tumors.
